Defrost fail?

Okay I have a 1980 with A/C that works (Baffled) but the defrost vent generates jack...I do not see any obstruction...Any ideas?

Most likely one of the vacuum lines to the a/c system has a leak. Check by the inspection lamp in the engine bay first, and then if you can't find it, you'd have to take the dash out and follow each line.

Grey hose...not really thick?
Like the one hanging from the bottom of my car that I cannot find a spot for?

Thanks =D
